SL74HC125
Quad 3-State Noninverting Buffers
High-Performance Silicon-Gate CMOS
The SL74HC125 is identical in pinout to the LS/ALS125. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LS/ALSTTL outputs.
The SL74HC125 noninverting buffers are designed to be used with 3-
state memory address drivers, clock drivers, and other bus-oriented
systems. The devices have four separate output enables that are active-
low.
